Product introduction
The YDJ 5kVA AC hipot tester , is a type of transformer in which the iron core and winding are immersed in transformer oil to enhance insulation and cooling conditions. This type of transformer uses transformer oil as insulation and cooling medium, which has the characteristics of excellent performance and low cost, and is therefore widely used in various power equipment. It is a device used for high voltage testing, widely used in insulation testing of power systems, voltage withstand testing of equipment, etc.
Product Principle Of YDJ 5kVA AC Hipot Tester
Basic principle: The working principle of 5kVA AC hipot testers is based on electromagnetic induction. It converts the input low-voltage AC power into high-voltage AC power through magnetic field coupling between the primary winding and the secondary winding. The insulation and cooling effect of oil: The winding and iron core of the transformer are immersed in insulating oil, which not only has good electrical insulation performance, but also plays a cooling role, preventing the transformer from being damaged due to heat during operation. High voltage output: By designing the winding turns ratio of the transformer, the input low voltage (such as 220V) can be converted into the required high voltage (such as tens or even hundreds of kilovolts) to meet the needs of high voltage testing. Formation of high-frequency electric field: During high-voltage testing, the high voltage generated by the secondary winding of the transformer will form a high-frequency electric field on the tested equipment, thereby testing its insulation performance.
